10 years is far too long for any regulatory document.
3 years is far too short.
Being an "out of towner" think of this, the 1976 NZ Electrical Regulations weren't updated until 1991 (and that was an amendment), but in all that time, we had quite a few new materials XLPE being one of them, introduced.
In 1977, the electrical industry here went metric, it didn't matter that the "codes" were still imperial.
Be careful what you wish for, you might just get it.
